Eukaryotes initiate DNA replication at multiple points in the chromosome, so replication forks meet and terminate at many points in the chromosome. Because eukaryotes have linear chromosomes, DNA replication is unable to reach the very end of the chromosomes. Due to this problem, DNA is lost in each replication cycle from the end of the chromosome.
The process of duplicating DNA is called DNA replication, and it takes place by first unwinding the duplex DNA molecule, starting at many locations called DNA replication origins, followed by an unzipping process that unwinds the DNA as it is being copied. However, replication does not start at all the different origins at once.
The coding region of a gene, also known as the coding DNA sequence (CDS), is the portion of a gene's DNA or RNA that codes for a protein. [1] Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene ...
During DNA replication, the replisome will unwind the parental duplex DNA into a two single-stranded DNA template replication fork in a 5' to 3' direction. The leading strand is the template strand that is being replicated in the same direction as the movement of the replication fork.
DNA polymerase III is then able to start DNA replication. DnaA is made up of four domains: the first is the N-terminal that associates with regulatory proteins, the second is a helical linker region, the third domain is a AAA+ region that binds to ATP, and the fourth domain is the C-terminal DNA binding region.

The 5′-untranslated region (5′-UTR) is a region of a gene which is transcribed into mRNA, and is located at the 5′-end of the mRNA. This region of an mRNA may or may not be translated, but is usually involved in the regulation of translation. The 5′-untranslated region is the portion of the DNA starting from the cap site and extending ...
The Pribnow box has a 6 bp region centered around the -10 position and an 8-12 bp sequence around the -35 region that are both conserved. [10] A CAAT box (also CAT box) is a region of nucleotides with the following consensus sequence: 5’ GGCCAATCT 3’. The CAAT box is located about 75-80 bases upstream of the transcription initiation site ...
Intergenic regions may contain a number of functional DNA sequences such as promoters and regulatory elements, enhancers, spacers, and (in eukaryotes) centromeres. [2] They may also contain origins of replication , scaffold attachment regions , and transposons and viruses .
